Rossini's semi-serious opera 'Torvaldo e Dorliska' belongs, like Beethoven's 'Fidelio', to the genre of 'rescue' opera. The hero and heroine of the title both succumb to the power of the villainous Duke, who has designs on the newly married Dorliska. Highlights include the heartfelt passages for the two lovers, such as the aria 'Dove son? chi m'aita?'
